- Patch #254166 by boombatower: improve and clean-up the test script.  Added color coding and allow people to control the verbosity.

  The "expert" will be a minimalistic profile for developers.  This opens
  the doors to add more things to the default profile and/or to create
  additional install profiles for core. It also helps set an example for
  more install profiles in the contributed modules repository.
